IMPROVEMENT IN ICE-CREAM FREEZERS.

Specification forming part of Letters Patent No. 181,972, datedSeptember 5, 1876; application filed July 10, 1876.

To all whom it may concern: Be it known that I, CHARLES W. PAGKER, ofPhiladelphia, Pennsylvania, have invented certain Improvements inIceCream Freezers, of which the following is a specification z Theobject of my invent-ion isto so construct a driving device for, and socombine it with, an ice-cream freezer, that the freezingvessel and itsadjuncts can be readily detached from, and as readily connected to, thesaid .-driving device without manipulating the coupling, and so that noprovision for securing the said vessel is required, a further object ofmy invention being the raising of the lid of the freezer without movingit away from the driving appliances.

In the accompanying drawing, Figure lis a side view, partly in section,of an ice-cream freezer and driving appliances; Fig. 2, a perspectiveview of the coupling device, and Fig. 3 a modified form of coupling.

rlhe freezer consists of the exterior vessel A containing the icc, theinner vessel B for containing the cream, a shaft, D, adapted to bear-vings on thel lid of the vessel A, and bevelwheels b b1, through whichmotion is communicatedto the vessel B from the driving device, all ofwhich parts -are common to other freezers.

The vessel A rests on a base, E, to which is secured a standard, F,having two bearings, ff, for a horizontal shaft, G, carrying a fly-vwheel, H, one end of the shaft being provided with a suitable handle, I,and the other end with a clutch, J, consisting of a lever with two arms,m and n, the former being provided with a pin, p, and the latter with acurved recess, q. A precisely similar clutch-lever, J',

once withdrawn from all connection with the driving applianceswithoutresorting to any preliminary manipulation of the coupling, and can be aseasily adjusted, so that its shaft D shall be in gear with thedriving-shaft G. It will also be seen that the clutches are such thatthe vessel A of the freezer cannot be distnrbed by the turning of theshaft G; hence there is no necessity for making any provision for thesecuring of the said vessel to the base.

It is not essential that the clutch-levers should be constructedprecisely as shown in Fig. 2. Oneof the levers, for instance, may havetwo curved recesses, and the other have two pins, as shown in Fig. 3;but I prefer the plan shown in Fig. 2, partly for the reason that onepattern onlyis required for both levers, but principally because itpermits the.

raising of the lid of the freezer without movl zontal driving-shaft Gr,and a freezer, A, with horizontal shaft D, arranged in line with thedriving-shaft, in combination with a clutching device constructed,substantially as described,

for permitting the Withdrawal and replacing of the freezer Withoutmanipulating the coupling.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. l

CHARLES W. PAGKER.
